It is modeled after Amsterdam's Red Light District.
It offers virtual nightclubs, hotels, bars, movie theaters and stores. There is a virtual currency called Rays, which members can earn and use it ingame. With that, you can buy apartments, gifts for other players and many other things. You can sell it for real currency. And it is a 3D world.
